PURPOSE: To investigate the preventive effect of intravitreal injection on posterior segment magnetic intraocular foreign body (IOFB)-related endophthalmitis, the risk factors for endophthalmitis, and the prognostic factors of posterior segment magnetic IOFBs.
METHODS: Retrospective analysis of patients with posterior segment magnetic IOFBs admitted to Hebei Eye Hospital (2014-2022). Among them, 172 patients (2016-2022) received intravitreal antibiotics at the time of primary repair. Rates of endophthalmitis in this cohort were compared with those in a previous cohort admitted between 2014 and 2016 (56 patients). In the previous cohort, patients received only primary repair.
RESULTS: The cohort was predominantly male (94%), median age 39 years. The right eye was affected in 105 patients (45%). The incidence of endophthalmitis was 4.7% (8/172) and 13.6% (8/59) in the recent and previous cohorts, respectively, with significant difference ( P = 0.043). Lens capsule rupture and IOFB >2 mm were risk factors for magnetic IOFB-related endophthalmitis ( P = 0.024 and P = 0.031, respectively). Lens capsule rupture (OR = 2.872, 95% CI: 1.487-5.548, P = 0.002), vitreous hemorrhage (OR = 2.010, 95% CI: 1.064-3.796, P = 0.031), retinal detachment (OR = 3.745, 95% CI: 1.758-7.979, P < 0.001), choroidal detachment (OR = 5.109, 95% CI: 1.465-17.808, P = 0.010), and IOFB >2 mm (OR = 1.914, 95% CI: 1.025-3.574, P = 0.042) were predictors of poor visual outcome.
CONCLUSION: Prophylactic intravitreal antibiotics can reduce the incidence of endophthalmitis in posterior segment magnetic IOFB injuries. Lens capsule rupture and IOFB >2 mm are risk factors for endophthalmitis. In addition, lens capsule rupture, vitreous hemorrhage, retinal detachment, choroidal detachment, and IOFB >2 mm are associated with a poor prognosis. A good initial visual acuity is associated with a good prognosis.
